Three Cliff Bay is one of the most photographed areas of Gower and is also commonly known as Three Cliffs. The bay takes its name from the three sea cliffs that jut out into the bay. Pennard Pill, a small stream, flows into the sea in the middle of the bay.

Individual beaches that make up this bay have their own names, including Pobbles Bay to the east of the Three Cliffs, and Tor Bay to the west. The beaches are separated at high tide but are accessible to each other at low tide on foot over the sands. Paths lead north to Pennard Burrows, east to Pobbles, and west to Tor Bay. Pobbles and Tor Bay are also accessible from the beach at low tide. When the tide is in however, it becomes impossible to cross the river heading towards Parkmill, so if you can't climb the sand dunes, take care not to get cut off as the tide sometimes comes in around the sides of the beach and leaves a sandy island in the middle - but not for long.

The beach is an important asset for locals and visitors and routinely qualifies for Blue Flag status. As a consequence, dogs are banned from the beach between May and September, however the beach is frequented by horses and their riders who enjoy a good gallop on the beach.

The 20 meter high limestone sea cliffs are a common feature that many climbers head for. The footpaths themselves include Walks up and down steep sand dunes, and the largest of the Three Cliffs is easily climbed if approached from the grassy base.
